Toall whom it may concern.: A Be it known that Il FRANcIs M. F. CAzIN,residin at Hoboken, in thc county of Hudson am Stale of New Jersey, haveinvented certain. new and useful Improvements in Machines andApparatusfor Manufacturing Filamenls for Electric Incandescent, Lamps,of which the following is a specification.

My present invention relates to an improved apparatus for forming orproducing filaments for electric incandescent lamps and itmorepariicularly seeksto provide' means for simultaneously squirting aplurality of semi-liquid plastic substances to form preferably a filletconsisting `of coneenirically arranged slraaco 'materials mposed of a'plurality Aof My invention also seeks to provide means for rapidlydryingthe' squirted fillet. and sirii'ultimeousljY winding or colli the samepreferably in the shape or formntlliat thev finlslied luminant-body isintended to' have.

I .Another object'J of my invention is to provide means-for passing anelectric current through the-fillet as it 'passes from thc squirtingreceptacles .which contain Athe different materials, to thereceptacles connected with the coiling mechanism, by means of whichcurrent the lilletJ may be testqiito give warn .ing of any interceptioninthe-.fillet 'and for Ianyother observations'useful in conducting v'theprogress of the processand'the aclionlof .the appara'iis.

shown in the drawings, forms a part ofthe sup orting base of the coilermechanism hereina ter more fully explained and this vessel H has for itsobject to receive steam therein throughthc pipe als which passes throughthe in ating ushing a" of the bottom'C and th. steam supply to thevessel li is regu-v lated by the valve a as shown. This vessel f Hserves as a heater to radiate heat into the s ace into which the filletis being squirted.

i bile I have shown this heater as a steamV heater, yet I desire itunderstood that the same may be used to burn charcoal therein,

for the production of the heat.

While I have shown the vessel H asia art of the base of the coilermechanism, yet de sire it understood that the heat-producing' vessel maybe an independent vessel and iocated anywhere within the bell-jar,without departing from my invention. Y

he mouth piece K before referred to is so designed as to give the filletthe desired cross4 sectional area and is made up of'essentially twoparts, the mouth piecelmember and a split ring K' and individual narrowsprings K with projections for entering the indentations fof thereceptacles.

It should be understood however, 'that I do not limit myself to theexact method of attachingdthese calibrating mouth piecesas any suita lemeans ma l be used, which will perform the desired unc-- tion and I alsodesire it understood that one or more of the vessels may be providedwith these calibrat` mouth pieces depending upon the condition of thefillet. I also dosire it understood that I do not limit'mynalf to theuse of the exact form of'calibrating,

From the foregoing it will be seen that the axial center of thestub-shaft 2h dos not coincide with the center of the gear 4 andtherefore when the internal gear housing is revolving the center of theshaft 2h will also describe a circle. As the local position of thecenters of the pinions or gears 2f"1d with respect to each other areconstant the gears will commence revolving as soon as the gear 4 comesinto contact with the rack portion 5 and rolls on it. Supposing thenumber of teeth in the gear 2*- to be equal to the number of teeth inthe rack section 5, the gear 2c and eoiling vessel 7 will make one fullrevolution around the axial line of the stub shaft 2" tbereb r formingthe small circular loop in the ilament around the conically shapedmembers' 1a. Continuing the rotationot' thegear 4Q over the are or angleB (see Fig. 6) the gear 2" will be' then without motion and the coilingvessel will rotate around its center V, Fig. 4, thereby forming the ovalshape part of the filament over the other core member 1'l of the recetacle. During this period of coiling the ibut plate 2 and the coilingvessel l are held in proper position with res ect to the housing 4' bthe locking stu or lug .8 s ring presse to its locking position. Toiminis l tbe friction in the gears and other parts, the whole spacebetween the housing` 4 and the base 3 is filled with any suitablelubricating material. Y When a small receptacle rotatable on acentral'vertical axis without the coiler mechanism, is used, it is onlynecessary to manipulate the lille-t by means of the guide R.

While I have shown the coiler mechanism as any automatically operatingmechanism yet a simple rotary receptacle may be used particularly whenit is desired to merely form a circular or hemispherical iillet or oneof a spiral form or any other mechanisms devisa le in mechanical art mavbe used for similarly moving the coiler. he receptacle or coiler it willbe noticed is provided with a groove or grooves d into which theissuingtillet i is caused to drop. The coiler mechanism is so formed andregulated as to move only with sufficient speed to take up the illet asit is scuirted into the receptacle 1, the speed .at w lich the fillet issquirted being regulated by regulating the pressure in the receptacles Eand F for forcing the materials therein connoticed that the mouth of thegroove i? is tained out through the mouth of the said receptacles.

By reference to the drawings it will be wider or funnel shape tocompensate for discrepancies in the mutual positions and speedsofoperation of the said parts.l The ceiling mec xanismperfomis'thevfunction 1st. by proyiding means for receiving the squirtedilament at the same rate ot length perstated time as it is ejected fromthemouth of the recepta cle, such rate of ejection being`r regulatedeither 'by regulating the pressure of the air before the materials inthe receptacles or by regulating the revolving speed or motion of thecoiler mechanism. 2nd, The coiler mechanism lserves to form the lletinto the individual shape desired.

brom the foregoing'it is apparent that for diflerent forms or shapes ofglowers not only dillerent tillet receptacles are requiredl but theposition of the receptacles can be varied with respect to the supportingparts being either eccentrical or concentrical, depending on the shapeor form of iilament desired.

One result obtained by the coiler mechanism is to hold both of the coilsand the uniformly cut parts thereof, while the same are beingtreated,-hardened or evenzually carbonized, until they are ready to beassembled in the complete lamp. To permit of ready access to the coilerfillet the envelop 1b may be made removable and is preferably composedof glass to permit inspection of the coiled material during theoperation of the apparatus and I may omit to use this envelop lJ ifdesired when the ceiling action is such that it can be dispensed with.Again when this envelop 1b lis not used, the coiled fillet is under thedrying influence of raretied air as before referred to and may be dustcoated by means of the dust ejector 0.

When the envelop 1b is used I may till the groove d with any suit-ableliquid which will preserve or serve a useful function with respect tothe fillet, provisionbeing made for the over-flow of such liquid in thehollow core members 1-l I may construct the coiler of any suitable.mechanism now known in the art to allow for passing current through theiilament.

While I have shown one of the receptacles E as loca-ted within the otherreceptacle l1", I do not desire it understood that such is the onlyposition they may assume vas both receptacles ma be held entirelywithout the bell jar H so ong as their ezzit ends are within the belljar and so long as their exit ends are practically in the samealine-ment so that the two fillets issuing simultaneously may be twirledor twisted to form a .single cord, thread or fillet and as such beguided into the coiler mechanism receptacle. Again while I have shownbut two rece tacles yet I desire it understood there may more or less,depending on the number of strata, of which it is desired to constructluminants.

In Fig. 7, I have shown a modified form of my invention in which Isuspend a bobblll S upon which is wound a fine metallic wire the end ofwhich, passing throng-h the squirting mouths, is secured to thereceptacle so that in the formation of the fillet the same will be 2.
